This study aims to reconstruct Grade 11 students' misconceptions about force through the Conceptual Change Model (CCM) making use of Predict, Discuss, Explain, Observe, Discuss, Explore, Explain (PDEODEE) tasks. This study was conducted using a mixedmethod approach. The participants in this study were 65 students (33 students in the experiment class--13 males and 20 females, and 32 students in the control class--12 males and 20 females) from a high school in Bandung, Indonesia. The instrument test used is the Four-Tier Test-formed Force Concept Inventory (4TT-FCI) with 8 question items. Three analyses were carried out: an analysis of students' misconception profiles during the pre-test and post-test, the reconstruction of students' misconceptions analysed based on percentage and codification using Great Change (GC), Not Change (NC), and Un-Great Change (U-GC). The improvement in students' conception was carried out using N-Gain with three categories (Low, Moderate, and High). The results show that the students' conception profile during the pre-test and post-test still detects misconceptions. However, these misconceptions can be ameliorated using CCM with PDEODEE tasks because the highest conceptual change is in the Misconceptions category (GC= 34.5) and the lowest is in the Un-Code category (U-GC= 2.4). The increase in the correctness of the conception was measured in the experimental class at 0.73 (High category), and the control class is 0.42 (Moderate Category).

The purpose of this study is to identify the difference between elementary pupils' higher order thinking skill (HOTS) in an environment learning using a variety of resources in a local culture-based learning. HOTS differences between those who use printed and electronic learning resources after controlling self-regulated learning pupil. This is an experimental quasi-research. Four groups of elementary school pupils from Ngada, Nusa Tenggara Timur, Indonesia, are the subject of the study. A three-dimensional self-reliance feature and 20 item of variable indicator descriptions are used to collect data, as is a high-level cognitive ability exam at the level of analysis, assessment, and invention of 10 item. To test the research hypothesis, the data was then examined using covariate analysis. A qualitative and descriptive analysis follows. A descriptive analysis is used to characterize the student's (high-level thinking) and deviation standards, whilst a qualitative analysis is used to explain high levels of thought profiles on elementary school thematic study. The results show a significant difference between students who are participating in incubation studies that draw on printed study resources and electronic study sources in terms of their high level of thinking capacity. Once the free learning variable was taken into account, the outcome indicated substance differences.

It is characteristic that besides other duties teacher competence management and development is becoming a part of school responsibilities. Still, school leaders lack the experience and instruments to accomplish these duties. From a teacher's perspective competence management and development can be seen as the process of identification and implementation of professional development (PD). An effective competence management approach that is widely used in business environments is the identification of required and actual competence profiles to judge which development is needed. Such a competence management approach isn't characteristic of school environments, still a promising perspective on how to solve challenges regarding teacher PD (TPD). TPD interventions are often criticized as being too general ("one size fits all" dominates); therefore, the search for practices on how to "tailor" PD initiatives to individual teacher needs is topical for TPD research. An effective way to personalize TPD could be the determination of TPD profiles and the design of the PD around these profiles. Person-centered approaches dominate in the identification of science teacher profiles, as surveys and tests are commonly used. Examples, of how the identification of science teacher profiles can be done using lesson observation data are missing. Science teaching is a complex process; to limit the complexity of this study, the authors focus on teaching that promotes student conceptual understanding (CU). A mixed method study was designed and conducted in a sample of 26 science teachers, who represented urban municipalities' science teacher population. The study included science teacher lesson observation and analysis, and determination of science teacher performance regarded teaching that promotes student CU. Science teacher performance data were used to identify teachers with similar performance across the selected criteria and to create science teacher profiles. A methodology for how lesson observation data can be used to identify teacher profiles in small teacher samples is described. Six various science teacher profiles in teaching that promote student understanding were identified, characterizing the variety of science TPD needs.

The purpose of this study was to address the role of social comparison in determining individual development by exploring the relationship of four types of social comparison with academic persistence-procrastination and subjective well-being among Chinese adolescents (n = 530, M[subscript age] = 14.59) from both variable- and person-centered perspectives. Results showed that the paths from social comparison to outcome were significant in most cases. Upward contrast (i.e., focusing on differences with superior targets) and downward identification (i.e., focusing on similarities with inferior targets) seemed detrimental, but upward identification (i.e., focusing on similarities with superior targets) and downward contrast (i.e., focusing on differences with inferior targets) seemed beneficial for adolescent development. Moreover, four social comparison profiles (moderate, 52.1%; high, 14.3%; upward contrast, 5.7%; and positive interpretation, 27.9%) emerged. The upward contrast profile was the least adaptive, and the positive interpretation profile (with high upward identification and downward contrast) was the most adaptive. This study provides new insights for understanding the role of social comparison in adolescent development and how to make more constructive use of it.

We aimed to identify unique constellations of sensory phenotypes for genetic etiologies associated with diagnoses of autism spectrum disorder (ASD) and intellectual disability (ID). Caregivers reported on sensory behaviors via the Sensory Profile for 290 participants (younger than 25 years of age) with ASD and/or ID diagnoses, of which [approximately] 70% have a known pathogenic genetic etiology. Caregivers endorsed poor registration (i.e., high sensory threshold, passive behaviors) for all genetic subgroups relative to an "idiopathic" comparison group with an ASD diagnosis and without a known genetic etiology. Genetic profiles indicated prominent sensory seeking in "ADNP," "CHD8," and "DYRK1A," prominent sensory sensitivities in "SCN2A," and fewer sensation avoidance behaviors in "GRIN2B" (relative to the idiopathic ASD comparison group).

Background: Current evidence indicates that intellectual disability and gender are both factors in differential usage of services. However, there are limited data about the demographic and service usage patterns of people with intellectual disability who use mental health services. This is particularly true in relation to women with intellectual disability with mental ill health. Interrogation of large-scale linked data sets can provide valuable insights into patterns of service usage among marginalised groups. Method: A large collaborative data linkage project was assembled with the overarching aim of providing an epidemiological profile of the health (including mental health), health service use, mortality and other service system contacts of people with intellectual disability in New South Wales (NSW), Australia. These linked data were used to interrogate the demographic, diagnostic and service use profiles of women with intellectual disability who have sought mental health support in NSW. Results: The linked data demonstrated important differences in patterns of diagnosis and service use for women with intellectual disability and mental health disorders, when compared to women without intellectual disability and men with and without intellectual disability, with mental health disorders. The diagnostic profile of women with intellectual disability reflected the gendered nature of diagnoses found in the wider population. Women with intellectual disability also experienced higher rates of diagnostic instability than other groups. Conclusions: The intersection between gender, intellectual disability and mental health has an effect on diagnostic profile and patterns of service use for women with intellectual disability. These differences are important and may impact targeted service delivery and planning for women with intellectual disability who have sought mental health support.

Following Richards's (2015) ideas of using movie clips, videos, and games as valuable technological tools for language learning, the present study was conducted to investigate the effectiveness of using novel extracts and computer game cutscenes based on the same story to develop the vocabulary knowledge of English as a foreign language (EFL) learners. The study employed a quasi-experimental design with a control group and an experimental group. Initially, both groups studied a target vocabulary list of 20 words and their definitions. The participants were asked to complete a multiple-choice definition matching test after studying the list to find out whether their levels of vocabulary knowledge were comparable prior to the applications. For the experimental group, a second vocabulary test equivalent to the first one was conducted after they read a novel extract including the target vocabulary items, and a third test was carried out after they watched two computer game cutscenes that were based on the same events as the novel extract to understand whether seeing the target vocabulary items in these contexts repetitively would result in a significant increase in their target vocabulary knowledge. For the control group, the second and the third vocabulary tests were undertaken immediately after the first one to investigate whether mere exposure to equivalent vocabulary tests without the interventions would lead to a significant increase in their target vocabulary knowledge. The findings of the study indicated that the scores of the participants in the experimental group increased descriptively on the second test and significantly on the third test, whereas the scores of the participants in the control group decreased significantly on the second test and descriptively on the third test. The study provides practical and academic implications based on the findings.

Since research integrity is not external to research but an integral part of it, it should be integrated into research training. However, several hindrances regarding contemporary research integrity education exist. To address them, we have developed a competency profile for teaching and learning research integrity based on four assumptions: 1) to include all levels of study (BA, MA, and PhD); 2) to integrate research integrity into research education itself; 3) to address research integrity issues in context-specific practices; and 4) to pay particular attention to the "grey zone" or questionable research practices. To assess the validity of the content of the competency profile and to determine if some adjustments to the profile are needed, we translated the competencies of the profile into items of a measurement instrument (a questionnaire) and conducted a survey amongst University of Ljubljana students that allowed us to: 1) obtain information about students' attitudes toward issues of integrity in research; 2) analyse differences in these attitudes among BA, MA, and PhD students; and 3) statistically validate the competency profile and suggest possible improvements. The results showed that: 1) students are highly aware of research integrity issues, as scores were high on all items assessed. However, there were some deviations to lower scores, especially in relation to questionable research practises, confirming our assumption that the "grey zone" issues are those that should be particularly addressed and given special attention in contemporary research integrity education. 2) The differences in the attitudes of BA, MA, and PhD students showed that higher-level students showed significantly more awareness of integrity issues than lower-level students did, suggesting that research integrity issues should be given special attention at the BA study level. 3) The measurement characteristics showed that the reliability of the questionnaire was very high, suggesting a good overall structure of the competency profile. The principal component analysis also confirmed the four-field structure of the Competency profile (Values and Principles, Research Practise, Publication and Dissemination, and Violations). However, the analysis also showed that the substructure of the four main areas of the profile did not fully match the results of the factor analysis, suggesting that the distribution of competencies in the competency profile could be reconsidered, especially in the area of Research Practice. The most recent developments in the field of research integrity also suggest that the competency profile should be updated with issues regarding the impact of artificial intelligence on research integrity.

This study examined 283 online learner dictionary definitions in terms of scores based on word frequency level and readability. Results revealed three findings. First, in terms of word frequency levels, definitions from the Cambridge learner dictionary incorporated fewer non-high frequency words (mid and low frequency words) compared to Oxford, Dictionary. com and Collins COBUILD learner dictionaries. Second, in terms of readability, definitions from the Random House learner dictionary were written at a significantly higher grade level compared to the other six online learner dictionaries. Third, in terms of both level of frequency words incorporated into definitions and readability grade level definitions, the Cambridge, Merriam-Webster and Longman online learner dictionaries were easier to understand compared to online learner dictionaries from Dictionary.com, Collins COBUILD, Oxford and Random House. Overall, the findings suggest both word frequency level and readability might contribute to the difficulty of online learner dictionary definitions.

Purpose: Limited research exists assessing speech perception in school-age children with speech sound disorder (SSD) and childhood apraxia of speech (CAS); despite early evidence that speech perception may lead to error-prone motor planning/programming. In this study, we examine speech perception performance in school-age children with and without speech production deficits. Method: Speech perception was assessed using the Wide Range Acoustic Accuracy Scale to determine the just-noticeable difference in discrimination for three consonant-vowel syllable contrasts (/b[open back unrounded vowel]/-/w[open back unrounded vowel]/, /d[open back unrounded vowel]/-/g[open back unrounded vowel]/, /[voiced alveolar approximant][open back unrounded vowel]/-/w[open back unrounded vowel]/), each varying along a single acoustic parameter for seven children with CAS with rhotic errors, seven children with SSD with rhotic errors, and seven typically developing (TD) children. Results: Findings revealed statistically significant mean differences between perceptual performance of children with CAS when compared to TD children for discrimination of /[voiced alveolar approximant][open back unrounded vowel]/-/w[open back unrounded vowel]/ contrasts. Large effect sizes were also observed for comparisons of /[voiced alveolar approximant][open back unrounded vowel]/-/w[open back unrounded vowel]/ contrasts between children with CAS, SSD, and TD peers. Additionally, large effect sizes were observed for /d[open back unrounded vowel]/-/g[open back unrounded vowel]/ contrasts between children with CAS and SSD and TD children despite nonsignificant mean differences in group performance. Conclusions: Overall, mean outcome scores suggest that school-age children with CAS and persistent rhotic errors demonstrated less accurate speech perception skills relative to TD children for the /[voiced alveolar approximant][open back unrounded vowel]/-/w[open back unrounded vowel]/ contrasts. However, the relatively small sample sizes per group limit the extent to which these findings may be generalized to the broader population.

During adolescence, increases in pubertal hormones lead to reproductive maturity as well as changes in cognitive development. Yet, little is known about how to best characterize interindividual differences in hormone concentrations. The goal of the current study was to examine the antecedents and consequences of membership in empirically derived hormone profiles. Data were drawn from 10,816 youth (48.1% female, M[subscript age] = 9.91, SD[subscript age] = 0.63) in the Adolescent Brain Cognitive Development (ABCD) study. Latent profile analysis (LPA) stratified by sex was used to derive hormone profiles using basal testosterone, dehydroepiandrosterone and estradiol (girls only). Eight profiles (four female profiles and four male profiles) were identified. They primarily represented differences in hormone levels (e.g., low hormonal milieus vs. high hormonal milieus), but also reflected discordance (e.g., high estradiol versus. high testosterone). There were limited sociodemographic differences, particularly after correcting for multiple comparisons, but youth with higher hormone milieus exhibited better inhibitory control, visuospatial processing and decision-making skills even after adjusting for age, pubertal status and demographic data. Thus, youth-centered approaches that focus on patterns of individual characteristics suggest that hormonal markers may provide unique information about associations between biological and cognitive development.

The current study investigated whether the difficulty in finding group differences in prosody between speakers with autism spectrum disorder (ASD) and neurotypical (NT) speakers might be explained by identifying different acoustic profiles of speakers which, while still perceived as atypical, might be characterized by different acoustic qualities. We modelled the speech from a selection of speakers (N = 26), with and without ASD, as a network of nodes defined by acoustic features. We used a community-detection algorithm to identify clusters of speakers who were acoustically similar and compared these clusters with atypicality ratings by naïve and expert human raters. Results identified three clusters: one primarily composed of speakers with ASD, one of mostly NT speakers, and one comprised of an even mixture of ASD and NT speakers. The human raters were highly reliable at distinguishing speakers with and without ASD, regardless of which cluster the speaker was in. These results suggest that community-detection methods using a network approach may complement commonly-employed human ratings to improve our understanding of the intonation profiles in ASD.

Bilingual children demonstrate varying levels of proficiency in each of the two languages to which they are exposed. Even though it is widely acknowledged that bilingual children are not a homogenous group, existing studies on dual-language profiles in bilingual children have focused on expressive language profiles. In this study, we used the normative data from the Quick Interactive Language Screener: English-Spanish (QUILS:ES; de Villiers et al., 2021; Iglesias et al., 2021) and latent profile analysis to identify dual-language profiles in receptive language skills in a large sample of Spanish-English bilingual preschoolers. We also examined demographic, dual-language experience, and home literacy environment factors that contributed to receptive dual-language profile membership. The optimal model represents a three-profile solution, including a balanced-low profile, an English-dominant average profile, and a balanced-high profile. Comparing participants' profile membership against their age and risk status for language impairment based on the QUILS:ES screening results, we found that while being in an older age group significantly increases a child's likelihood of being in a balanced-high profile, an older child displaying a balanced-low profile is at a higher risk for language impairment. Age, socioeconomic status, and home literacy environment factors were found to be associated with strong dual-language skills, whereas (relative) dual-language experience did not predict profile membership. Together, these findings extend previous work that examined the heterogeneity within Spanish-English bilingual children by demonstrating substantial variability in their receptive language skills and providing insights into malleable factors that may be targeted to support dual-language development.

Research is scarce about the lexical processes undertaken by thousands of L2 learners worldwide who already command one or more languages. Some aspects involved in lexical organisation and production, such as clustering and switching, have been traditionally approached through manual methods, which depend on subjective judgments of semantic relatedness between words. The present study seeks to provide a more objective exploration of EFL lexical production and organisation strategies of two rather similar groups of 12th grade learners of EFL as L2 and L3 via a distributional semantic analysis of semantic fluency. In addition to common measures of vocabulary performance, such as number of words produced, a series of lexical organisation and production strategies along with global and local semantic relatedness metrics will be examined. No differences were found about word frequency. While the L3 group used more word classes and cognates, and produced more idiosyncratic responses, the L2 group excelled in most semantic relatedness variables. These results might be due to the presence of the third language in the L3 group, which might be partly interacting with the other background languages. Evidence on these aspects may inform the development of precise language learning strategies adapted to the learner's linguistic profile.

With the increased emphasis on the benefits of self-regulated learning (SRL), it is important to make use of the huge amounts of educational data generated from online learning environments to identify the appropriate educational data mining (EDM) techniques that can help explore and understand online learners' behavioral patterns. Understanding learner behaviors helps us gain more insights into the right types of interventions that can be offered to online learners who currently receive limited support from instructors as compared to their counterparts in traditional face-to-face classrooms. In view of this, our study first identified an optimal EDM algorithm by empirically evaluating the potential of three clustering algorithms ("expectation-maximization," "agglomerative hierarchical," and "k-means") to identify SRL profiles using trace data collected from the Open University of the UK. Results revealed that agglomerative hierarchical was the optimal algorithm, with four clusters. From the four clusters, four SRL profiles were identified: poor self-regulators, intermediate self-regulators, good self-regulators, and exemplary self-regulators. Second, through correlation analysis, our study established that there is a significant relationship between the SRL profiles and students' final results. Based on our findings, we recommend agglomerative hierarchical as the optimal algorithm to identify SRL profiles in online learning environments. Furthermore, these profiles could provide insights on how to design a learning management system which could promote SRL, based on learner behaviors.

Interface properties have been found to exhibit protracted instability in advanced bilingualism and L2 learning (Sorace, 2000, 2005; Sorace & Filiaci, 2006). This study examines the role of learning context in modulating this instability in an interface property, namely the interpretation of definite plurals in L2 Arabic. Generic readings in English preverbal positions are expressed with bare plurals, which are ungrammatical in Arabic. Performances of two advanced English-speaking learners of Arabic in two learning contexts are compared: formal language instruction in an at-home (AH) setting and an extended study abroad (SA) setting. Results of two elicited production tasks reveal that whereas the advanced-AH group fluctuated between bare plurals (arguably transferred from L1) and definite plurals, the advanced-SA group opted for definite plurals. These results confirm Sorace's (2011) claim that protracted instability is real in interface properties in advanced bilingualism. They further suggest that input conditions and learning context play a crucial role in overcoming this instability. Active contact with the L2, which is characteristic of extended SA settings, is suggested to stabilize L2 forms and preempt competing L1 forms in interface properties.

High and low achievers' strategy use profiles in the speaking skill appear to be rare, with the few studies examining their strategy use profiles only in skills such as reading and writing. Another gap can be observed in the scrutiny of effective and ineffective strategy use in speaking tests. The study was carried out with thirty male and female high and low achieving test takers who engaged in the speaking section of IELTS and reported their strategy use through stimulated recalls in the Iranian context. Data collection involved two key phases: The test takers first went through a familiarization phase where they learned how to carry out stimulated recalls. This phase was followed by the main phase of the study where the test takers took the IELTS speaking exam, verbalizing their strategies after each of its three speaking tasks. The researchers used Huang's (2013) taxonomy of speaking strategies to analyze the garnered data. Results indicated high achievers' heavier reliance on strategic behaviors compared with low achievers. The findings also revealed high achievers' greater use of effective strategies than low achievers, and low achievers' more frequent use of a noticeably higher number of ineffective strategies compared to high achievers. More specific outcomes revealed that the variations between the two groups were mainly in the frequency of meta-cognitive, communication, approach, and social strategy categories. The results primarily confirm high and low achievers' varied strategic behavior profiles in test situations and the significance of effective strategy employment for higher test scores.

This study investigated if the language profiles of prelingually deaf children with bilateral cochlear implants (CIs) and children with typical hearing (TH) matched on their quantitative score on clinical spoken expressive language tasks differed in terms of sentence complexity, sentence length, and severity of grammatical errors. No significant differences were found between the groups in terms of (1) proportion of simple, conjoined, and complex sentences; (2) mean length of utterance based on words and syllables; and (3) proportion of local and global grammatical errors. The results indicate that the quantitative scores on the clinical spoken expressive language tasks are related to similar spoken language profiles in children with CIs and children with TH. These findings suggest that these tests can be used for meaningful comparisons of expressive spoken language skills. However, more studies are needed on the real-life expressive language skills of children with CIs, as clinical tests often rely on one specific modality (in this study: spoken language) and might therefore not accurately represent the language skills of the children.

Children start preschool with large individual differences in their early numerical abilities. Little is known about the importance of heterogeneous patterns that exist within these individual differences. A person-centered analytic approach might be helpful to unravel these patterns and the cognitive and environmental factors that are associated with them. We applied a person-centered approach to a 5-year longitudinal study (N = 410, 213 boys) conducted in Belgium from preschool to grade 3. Preschoolers (M[subscript age] = 58.14 months, SD[subscript age] = 3.51) were selected to represent the full range of socioeconomic backgrounds. We examined via Latent Profile Analysis the heterogeneous patterns that exist in preschoolers' early numerical development using measures of counting, numeral identification, comparison, ordering, and arithmetic abilities. We investigated the association between the derived numerical ability pathways, general cognitive factors (working memory, language, spatial ability) and the home math environment. We also evaluated the relation of these early numerical ability pathways to later mathematics achievement in grade 1 and 3. Four longitudinal pathways emerged: a low (15%), below-average (28%), above-average (44%), and a high numerical ability pathway (13%). Differences between the four pathways were mostly quantitative. Most of the general cognitive factors contributed to pathway membership, whereas the home math environment and socioeconomic status (SES) did not. The pathways differed in mathematics achievement in grade 1 and 3, and most of these differences remained when the covariates were considered. The results highlight the heterogeneity that is already present in preschoolers' numerical abilities and their predictive value for subsequent mathematics achievement.

The dynamics of the labour market are characterized by several important aspects such as: the emergence of new trades and the disappearance of others, the emergence of the phenomenon of technology, of the tendency to replace the human activity with the computerized activity in many fields, the replacement of office work with telework, the replacement of the physical space of professional activity with the virtual space. According to these considerations, the school should provide support to adolescents by applying counselling strategies in their choosing of a career. The novelty compared to the previous studies is that the present research provides a dynamic perspective in counselling adolescents on the approach of a career, which is based on a quadric-dimensional model, founded on four determining vectors for the career decision-making: identification of the problem, analysis of the individual profile, analysis of the socio-economic environment and projection of the career plan (involving the completion of some activities), which can be achieved over time whenever indecision or any other change occurs. The counselling model sets out an applicable approach whenever the adolescent faces fluctuating occupational interests against the background of social and economic uncertainties plus the prospect of a poor self-knowledge of their own resources but also an insufficient analysis provided by the school in relation to the labour market. This research is advancing the hypothesis that counselling and guidance services are supposed to be valued as important by most educational factors. From this perspective, in the descriptive study undertaken, we engaged the methodology of the questionnaire and observation and the results obtained reinforce the idea that school is the main factor that can determine the career success of the adolescent. The quadri-dimensional model of counselling the adolescents in choosing a career can be an effective tool in terms of the ratio of the results obtained from the application to the effort involved.

The development and improvement of effective tools for predicting human behavior in real life through the features of its virtual activity opens up broad prospects for psychological support of the individual. The presence of such tools can be used by psychologists in educational, professional and other areas in the formation of trajectories of harmonious person's development. Currently, active research is underway to determine psychological characteristics based on publicly available data. Such studies develop the direction of "Psychology of social networks". As markers for determining the psychological characteristics of people, various parameters obtained from their personal pages in social networks are used (texts of posts and reposts, the number of different elements on the page, statistical information about audio and video recordings, information about groups, and others). There is a difficulty in obtaining and analyzing a data set this big, as there are non-linear and hidden relationships between individual data elements. As a result, the classic methods of information processing become inefficient. Therefore, in our work to develop a comprehensive model of success based on the analysis of qualitative and quantitative data, we use an approach based on artificial neural networks. The labels of the input records are used to divide the subjects of the study into five clusters using clustering methods (kmeans). In the course of our work, we gradually expand the set of input parameters to include metrics of users' personal pages, and compare the results to determine the impact of qualitative parameters on the accuracy of the artificial neural network. The results reflect the solution of one of the tasks of the research carried out within the framework of the project of the Russian Science Foundation and serve as material for an information and analytical system for automatic forecasting of human life activity based on the metrics of his personal profile in the social network VKontakte.

Court instructions and public perception endorse that eyewitness evidence provided by police should weight more heavily than laypeople's in court. Evidence is inconsistent. The current experiment provides a nuanced analysis of identification performance of police and laypeople at different levels of confidence. Laypeople and advanced police trainees (N = 192) viewed portrait, profile, and body-only lineups for central and peripheral targets. Police trainees displayed higher hit and correct rejection rates than laypeople for portrait lineups, and higher correct rejection rates in profile lineups for central targets. Calibration was similar for both groups, although police trainees had an advantage at low target presence base rates. Calibration was best for central targets' portrait and profile lineups. Participants displayed poor calibration and strong overconfidence for body-only lineups and peripheral target lineups. We conclude that experience and specialization of police might be important when investigating a possible superiority of police who serve as eyewitness.

Research experience is widely used in quality assurance exercises to benchmark postgraduate education at the institutional level. However, individual differences in students' research experience have been largely neglected. Furthermore, little is known about how differences in students' research experience are associated with skill development and overall satisfaction. This study addressed these gaps using an explanatory sequential mixed-methods design. Study 1 was a quantitative study that involved surveying 590 research postgraduate students (i.e. 421 PhD and 168 MPhil students). A person-centered approach, specifically latent profile analysis, was used to analyze the data. Our findings revealed that students could be divided into three groups based on their research experience: rewarding, ordinary, and unsatisfactory. Those with a rewarding research experience experienced greater development in their skills and higher levels of satisfaction, while those in the unsatisfactory group demonstrated the worst outcomes. Study 2 was a qualitative study that involved interviews with 10 PhD students. The qualitative findings largely triangulated the quantitative results but also uncovered emerging themes, including the importance of student-supervisor misfit, publication pressure, and the COVID-19 pandemic context. Theoretical and practical implications of these findings are discussed.

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children, and they tend to make errors involving the relativizer DE and are more likely to produce Non-RC responses. Furthermore, the gap type of RC or the adjective's position does not affect our participants' recall of the test sentences. We conclude that the symmetric performance of our participants in the subject RC and object RC conditions is because the structural intervention occurs in object RCs, but the linear intervention counts more in subject RCs. The syntactic deficit approach better explained the difficulty experienced by children with DLD in RC repetition. Theoretically, this study demonstrates that the Edge Feature Underspecification Hypothesis captures more characteristics of children with DLD in repeating RCs than previous representational theories.

Using the ECLS-K:2011, a nationally representative dataset, we compared measures of behavioral engagement among students with four different learning profiles: students identified with learning disabilities, students identified as gifted, students identified as both gifted and having a learning disability (twice-exceptional; 2e), and general education students. Behavioral engagement focuses on conduct in class, participation in school-related activities, and interest in academic tasks. We detected differences in engagement among the four learner profiles, specifically when comparing students with disabilities to other profiles. When comparing students with disabilities and general education students to gifted and 2e students, the effect size was medium to large. The effect size between the gifted and 2e profiles was small, suggesting similar behavioral engagement. Because disabilities and giftedness can often "mask" each other, these findings suggest that recognizing how behavioral engagement manifests in each category can lead to more accurate identification of special-needs students for GT assessment.

Given the ongoing development of computer-based tasks, there has been increasing interest in modelling students' behaviour indicators from log file data with contextual variables collected via questionnaires. In this work, we apply a latent regression model to analyse the relationship between latent constructs (i.e., performance, speed, and exploration behaviour) and contextual variables among Scandinavian students (i.e., Norway, Sweden, and Denmark) during their completion of three interactive mathematics tasks in the 2012 Program for International Student Assessment (PISA). The purpose of this study is threefold: (1) to investigate whether a factor model is adequate for explaining the relationship between extracted process indicators from log files and students' performance on the three items; (2) to evaluate whether measurement invariance holds for the three analysed countries; and (3) to determine how well contextual variables [i.e., a student's background, availability, use of information and communication technology (ICT) resources, and learning conditions for mathematical literacy] correlate with the model's latent constructs. Our findings reveal that a three-factor CFA model is well-suited to the analysed data and that a weak measurement invariance model performs best. By including contextual variables in the modelling, we also highlight the differences in Scandinavian students' profiles. Specifically, higher economic social cultural status (ESCS) consistently led to higher math proficiency across all three countries. Norway did not show any gender differences in math proficiency, response time, or exploration behaviours. Experience with math tasks at school led to more exploration behaviours across all three countries. Swedish and Norwegian students who had more experience with pure math tasks at school were likely to obtain higher mathematics achievement scores and tended to interact more frequently with the testing platform when answering the three math items. When Danish students had higher ICT scores (i.e., more ICT resources available at school and home), they had lower response accuracy. There was, however, no effect of ICT on the three factors among Swedish and Norwegian students. Finally, we also discuss the implications and limitations of this study.

Background: Some data call into question the persistence of developmental language disorders (DLDs) identified during the preschool period. For this reason, speech-language pathologists (SLPs) often reassess children. However, it is unclear if the instability of the profiles documented in community sample studies is present in children referred to specialized clinics. Given the scarcity of SLP resources, is re-evaluating the language skills of these children a good use of clinical time? Aim: To examine the stability of the findings from two SLP assessments in a sample of Canadian preschool children referred to a tertiary clinic between the ages of 2 and 6 years. It was hypothesized that children under the age of 4 years at first assessment and children with less severe initial deficits would show less stability of DLD diagnosis. Methods & Procedures: The clinical files of children referred to an early childhood psychiatric clinic in Canada were reviewed. For 149 children with two SLPs assessment reports, persistence of language deficits was documented and tested with McNemar's statistics. Differences between preschoolers under the age of 4 versus 4 years and over, as well as between mildly and severely impaired children, were examined. Outcomes & Results: High level of agreement (94%) and McNemar's test (p = 0.180) supported the stability of initial diagnosis. The stability for children assessed before the age of 4 (n = 64) was 100%, and was significantly different from older children's (n = 85) stability of 89% (Fisher's exact test, p = 0.01; bilateral). The stability for children with mild impairments (n = 18) was 78%, which was significantly lower than the stability (97%) in children with severe impairments (n = 114) (Fisher's exact test, p = 0.007; bilateral). Conclusions & Implications: No instability of language status was observed in children assessed before 4 years of age, which could be related to the significant severity of the difficulties that children in this age group presented and be specific to this type of clinical sample. The great stability of language status observed in preschoolers referred to a specialized clinic suggests that clinicians should limit reassessments to devote available resources to intervention efforts.

Besides being promoted as a way to improve target language proficiency, Content and Language Integrated Learning (CLIL) is also believed to positively impact socio-affective variables such as language attitudes and motivation. Yet, few extensive empirical studies exist on these aspects in CLIL. The present contribution aims to address this gap in the literature by investigating language attitudes and motivation in CLIL on a large scale across two target languages (English and Dutch) and two instruction levels (primary and secondary). Questionnaire data were collected from 896 pupils in French-speaking Belgium measuring their language attitudes in terms of perceived easiness and attractiveness of the target language and their motivation in terms of expectancy for success, task value and cost. Results of the MANCOVAs show pupils report more positive attitudes and higher motivation in CLIL compared to non-CLIL and in English compared to Dutch. However, these differences mainly appear at secondary level, suggesting more favorable profiles develop after the fifth grade, which is the onset of formal foreign language instruction for non-CLIL pupils. Moreover, the effect sizes indicate that the target language (English vs. Dutch) plays a more crucial role than CLIL vs. non-CLIL regarding language attitudes and motivation.

Purpose: This study (1) used a person-centered approach to identify specific subgroups of 1,265 EFL learners who participated in Informal Digital Learning of English (IDLE) activities, and (2) looked at how different IDLE profiles are related to important affective variables. Design/Methodology: To identify IDLE profiles, we used cluster analysis. Findings: The L2 motivation, L2 enjoyment, L2 anxiety, and grit levels of the IDLErs with distinct profiles differed significantly. When compared to Profiles 1 (Minimal IDLErs: 33%), 2 (Gaming-Entertainment IDLErs: 16%), and 3 (Entertainment IDLErs: 30%), both Profile 4 (Maximal IDLErs: 11%) and Profile 5 (Entertainment-socializing IDLErs: 10%) demonstrated significantly higher scores on Ideal L2 self, L2 enjoyment-self, L2 enjoyment-others, L2 communication anxiety-offline, and Grit. Profiles 4 and 5 made full use of out-of-school digital environment, which provided several affective benefits for EFL learners. Originality/value: Methodologically, the analytical and statistical approach could help to move informal language learning research one step closer to being more person-centered. In practice, the various IDLE profiles identified in this study may be of interest to EFL teachers in order to better understand their students' IDLE activities outside of school and to inform classroom teaching and learning.

Universities worldwide are beginning to counter the prevailing neo-liberal ideology by paying renewed attention to the moral development of students and fostering their life purposes. This mixed methods study investigates the life purposes of higher education students in four institutions in the Netherlands (n[subscript Dutch] = 663) and Finland (n[subscript Finnish] = 846). Based on quantitative data, we identified four purpose profiles: purposeful, self-oriented, dreamer, and disengaged. Qualitative data showed that students' willingness to contribute to a better world was not particularly prominent. An exception was found in the data of a Dutch research university working with a specific worldview and value base and emphasizing moral education. We conclude that universities need to put more effort into educating young professionals whose life purpose goes beyond their self-interest and who are willing and able to address pressing societal and global problems. This particularly includes professionals in the domains of technology and economy.

In the current study, we used latent profile analysis to investigate the Dimensional Clinical Personality Inventory 2 capacity to discriminate psychopathy traits in a sample of adults. Participants were 628 adults from the general population recruited by convenience. Our latent profile analysis recovered two groups: Psychopathic Tendencies and Empathetic Tendencies. The psychopathic tendencies group scored higher in all the IDCP-2 factors comprising psychopathy features. Although our study has sample restrictions, we found evidence for using IDCP-2 factors to discriminate people with low and high levels of psychopathic traits. We discuss the theoretical and practical implications of our findings.

In this quasi-experimental study, the effects of lexical coverage through pseudo word manipulation in dialogue comprehension are investigated. Forty-four first-year students in a Japanese university listened to five dialogues at different lexical coverage levels: 98%, 95%, 90%, 85%, and 83%. The results of the comprehension tests confirm the results seen in narrative, monologic lexical coverage studies that it is possible for intermediate EFL learners to attain adequate listening comprehension on texts with as little as 90% lexical coverage. However, variation in participants' scores on higher lexical coverage dialogues suggest pseudo word distribution and topic familiarity might be acting as confounding variables in lexical coverage studies which use pseudo word manipulation. Suggestions for methodological reform for future projects on this subject are provided.

The purpose of this cluster randomized group study was to investigate the effect of multitiered, dual-language instruction on children's oral language skills, including vocabulary, narrative retell, receptive and expressive language, and listening comprehension. The participants were 3- to 5-year-old children (n = 81) who were learning English and whose home language was Spanish. Across the school year, classroom teachers in the treatment group delivered large-group lessons in English to the whole class twice per week. For a Tier 2 intervention, the teachers delivered small-group lessons 4 days a week, alternating the language of intervention daily (first Spanish, then English). Group posttest differences were statistically significant, with moderate to large effect sizes favoring the treatment group on all the English proximal measures and on three of the four Spanish proximal measures. Treatment group advantages were observed on Spanish and English norm-referenced standardized measures of language (except vocabulary) and a distal measure of language comprehension.

Early language competence is a reliable and powerful predictor of children's success in school, and word gaps linked to socioeconomic status disparities have cascading effects on academic outcomes. While early research -- such as the work of Hart and Risley (1995) -- focused on gaps in vocabulary, growing evidence reveals wide gaps in syntax as well. Language is an interdependent developing system of vocabulary, syntax, and language processes, yet existing research has not evaluated how SES gaps compare for these language components or how these components are linked for children from lower- and higher-SES families. Such a profile is sorely needed to understand the course of language development in all children.A new language measure, the Quick Interactive Language Screener (QUILS), expands on other measures by evaluating preschoolers' vocabulary and syntax knowledge, along with their language-learning process skills. This screener was administered to a large, diverse sample of English-speaking children ages 3 through 5. Results indicated that the effect of SES was significant and comparable for all three language components, at all ages tested. Additionally, correlations among syntax, vocabulary and process were robust for low- and mid-SES children. These findings highlight the importance of looking beyond vocabulary to language syntax and process to better understand the SES gap in language.

WhatsApp has significantly penetrated the various spheres of peoples' lives all over the world. The purpose of this study is to look at two aspects of WhatsApp text-based status notifications; namely, the most common discursive realizations and the major pragmatic themes. A sample of 846 status notifications for WhatsApp users' profiles was analyzed. Data, which were gathered between January and March 2017, were from three sets of male and female users. The status notifications were qualitatively analysed in terms of both the most common discursive realizations and pragmatic themes. The major findings of the study showed a variety in the discursive realizations, including self-generated statuses, which marked 82%, and auto-generated statuses, which made 18%. Data revealed also that the most used type of the self-generated was the pure text, which marked 53%. In terms of the major pragmatic themes employed by the users, data showed four main categories: religious, social, personal and national. The findings were then discussed, justified, and compared with results from previous research. The paper concludes with the limitations and future research recommendations.

Given that Roma students are underrepresented in higher education, and that few studies investigated personal and social resources of young Roma adults, our aim was to explore the psychological and social capital of Roma attending college and determine if there are differences compared to non-Roma students. In total, 89 Roma and 105 non-Roma college students filled in the questionnaire. Significant differences between the two groups were obtained for all components of psychological capital, except for self-efficacy. Roma students' family financial and educational status was significantly more unfavorable than that of the non-Roma students. They received support from fewer persons to pursue higher education but have been more civically engaged and received more support from NGO representatives. We can conclude that, despite unfavorable family structure capital, Roma college students have developed a high level of psychological capital. Practical implications are furthered elaborated.

Children with autism often display discrepancies in their intellectual functioning, with nonverbal skills frequently being more developed than verbal. Compared to monolingual autistic children, however, much less is known about how bilingualism affects intelligence in autism. The current study examined the intelligence profiles of 146 bilingual and 170 age- and gender-matched monolingual children with autism (6-17 years) using the Wechsler Intelligence Scales for Children-Third Edition, by tracking cluster profiles across children and by modeling verbal and nonverbal IQ performance in each cluster as a function of language experience (monolinguals vs bilinguals), socioeconomic status, and age. The results reveal that socioeconomic status, operationalized as mother's years of education, mediated by bilingualism was strongly related to autistic children's intelligence. Low-socioeconomic status bilingual autistic children exhibited better performance than their monolingual peers across both the verbal and nonverbal intelligence subtests. However, the difference found in the intelligence profiles between monolinguals and bilinguals belonging to high-socioeconomic status was limited to the Comprehension Wechsler Intelligence Scales for Children test, with high-socioeconomic status monolingual autistic children outperforming their bilingual peers. The findings highlight the importance of investigating bilingualism effects in relation to socioeconomic status in autism.

Mathematics teachers' teaching beliefs play an important role in instructional practices and students' achievement. In China, transmissive teaching beliefs were prevalent before 2001. Since then, a student-centered concept has been advocated in the national curriculum reform; however, few studies have assessed contemporary Chinese mathematics teachers' teaching beliefs during the 20 years since the reform. In the current study, we elucidated the teaching beliefs Chinese teachers hold and their effects on instructional practices and students' mathematics achievement. A total of 1463 mathematics teachers and 12,437 students in grade 4 were recruited from Beijing, Shanghai, Jiangsu, and Zhejiang in Eastern China. Based on self-reported teaching beliefs using a short revised version of the Teacher Education and Development Study in Mathematics (TEDS-M), the study identified that contemporary Chinese teachers usually hold constructive teaching beliefs. In comparison, transmissive teaching beliefs showed significantly higher scores for teachers with more than 20 years of teaching experience. Moreover, male teachers and those with more teaching experience were more transmissive, but the effect of gender was small. The indirect effect of teachers' teaching beliefs on students' mathematics achievement through perceived constructive instructional practices was revealed using a multilevel structural equation model. This study illustrates the teaching beliefs of Chinese mathematics teachers and their effects, using evidence collected from a more general perspective.

The overall purpose of this study was to examine caregivers' adherence to a storybook-reading intervention using latent class analysis (LCA). This study also examined whether adherence was related to child and family characteristics including children's language ability, caregiver education, and whether the child has a disability. Caregivers of children with language impairment (N = 695) were provided with a book per week and were encouraged to read the book twice a week. Results of the LCA indicated that there were four profiles of caregivers' adherence: sporadic, late dropout, completers, and early dropout. Completers were so-named because they adhered to study activities for the duration, completed the study as designed. These caregivers represented one third of participants, whereas dropouts (both early and late) represented the majority of caregivers (51%). This study found no reliable differences in the adherence patterns for caregivers of children with a disability and their typically developing peers. However, children who had better language skills also had significantly higher probability of continued caregiver adherence. Implications for educational research are discussed.

Based on the Communicative Action Theory, intersubjectivity theory and the interpersonal classification of metadiscourse, this study makes a comparison between the source texts and the English-translated texts of Chinese company profiles with a self-built parallel corpus, along the dimensions of lexical variation, lexical density, grammatical explicitation and metadiscourse use. The purpose of this study is to evaluate English-translated company profiles by examining the lexical features and intersubjectivity. The research findings are as follows. First, English company profiles show a lower degree of lexical variation and density and a higher degree of grammatical explicitation, and use more metadiscourse resources. Second, metadiscourse resources construct the intersubjectivity of company profiles by fulfilling the Universal Validity Claims required by communicative actions. Third, English-translated company profiles are much easier to understand, with a clearer logic and a higher degree of intersubjectivity.

This research addresses the profile and motives for enrollment of online master's students in three different fields of knowledge (humanities, social sciences and experimental sciences) at an online university. The data has been collected through an ad hoc questionnaire; the sample, obtained of 253 UNIBA master's students, has been analyzed using a descriptive methodology and a factor and comparative analysis of the investigation dimensions. The results include the different access profiles of the students that have been identified based on a set of sociodemographic variables. Furthermore, the differences between their motives for enrolling and the latent factors that can be identified. These results are discussed, and compared to traditional, face-to-face, master's degrees, which have had an extremely increase on enrollment in the last few years. The importance of guidance and tutoring are examined as tools to guarantee quality standards and support student's perseverance and overall success.

The Peabody Picture Vocabulary Test (PPVT) is a widely used test of receptive vocabulary, but no researchers to date have examined the performance of low-educated, low-literate L2 adults, or compared these individuals' performances to their more highly educated peers. In this study, we used many-facet Rasch analysis and mixed-effects linear regression to determine the impact of educational background and other demographic variables on PPVT test performance. The analyses rely on the performance data of 1,014 adult learners of Dutch as a second language on the Dutch version of the PPVT (PPVT-III-NL). The results show that a substantial proportion of score variance can be attributed to educational background variables and to the educational tracks the participants followed. These tracks, which cater to the needs of different L2 learner profiles, appear to exacerbate rather than mediate any performance differences. Although this study provides evidence of performance differences and differential item functioning resulting from linguistic, demographic, and educational variables, it offers no data to invalidate the use of the PPVT on low-educated L2 adults.

Purpose: Script training is a well-established treatment for aphasia, but its evidence comes almost exclusively from monolingual English speakers with aphasia. Furthermore, its active ingredients and profiles of people with aphasia (PWA) that respond to this treatment remain understudied. This study aimed to adapt a scripted-sentence learning protocol to Colombian Spanish speakers with aphasia, investigate speech entrainment (i.e., unison production of sentences) as an active ingredient for scripted-sentence learning, and identify patient profiles associated with better scripted-sentence learning. Method: Fourteen monolingual Spanish speakers with aphasia learned a set of 30 sentences. To examine speech entrainment as an active ingredient for scripted-sentence learning, we investigated whether sentences containing externally added rhythmic cues (involving stress-aligned vs. metronomic rhythmic cues) would result in better scripted-sentence learning compared with control sentences. Learning was measured via postsession probes and analyzed using mixed-effects logistic regression models. The relationship between scripted-sentence learning and baseline language and rhythmic processing measures was also examined. Results: Significant scripted-sentence learning over time indicated a successful adaptation of a script-training protocol to Spanish. PWA learned significantly more scripted sentences in the rhythmically enhanced conditions compared with the control condition. There were no differences between rhythmically enhanced conditions (stress-aligned vs. metronomic). In terms of patient profiles, it was found that PWA with more severe aphasia demonstrated larger learning gains, but rhythmic processing showed little association with learning estimates. Conclusions: To our knowledge, this study provides the first adaptation of a scripted-sentence learning protocol for monolingual Spanish speakers with aphasia, demonstrating cross-linguistic benefits of script training interventions. Highlighting rhythmic features during speech entrainment facilitated scripted-sentence learning in Spanish speakers with aphasia, suggesting that speech entrainment may be an active ingredient for scripted-sentence learning. More severe aphasia was associated with better scripted-sentence learning, suggesting that more severely impaired individuals are likely to benefit most from this treatment.
